PHILIP RIEDELE, OF LOS ANGELES, CALIFORNIA, ASSIGNOR TO UNITED- STATES SPRING COMPANY, INC., OF LOS ANGELES, CALIFORNIA, A CORPORATION OF CALIFORNIA.

BUMPER.

Application filed May '31, 1918. Serial No. 237,608.

To all whom it may concern:

Be it known that I, PHILIP RIEDELE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Bumpers, of which the following is a specification.

My invention relates to bumpers and consists in the novel features herein shown, described and claimed.

Specifically, my object is to make a wooden bumper or fender for automobiles and the like, the ends of the bumper having faces which are straight vertically and semi-circular horizontally or around vertical axes so as to reduce the liability of the end faces catching an obstruction and splitting the woocl.

Figure 1 is a top plan view of a bumper embodying the principles of my invention.

Fig. 2 is an enlarged fragmentary rear elevation, as seen on the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary perspective of the end of the bumper shown in Figs. 1 and 2.

Fig. 4 is a plan of one end and showing a ca 9.

fhe main body of the bumper is formed of a straight-grained piece of wood out straight and of the desired length and rectangular in cross-section, and the finished stick comprises the straight central portion 1 and the horns 2 and 3 extending from the ends of the central portion. The horns 2 and. 3 are formed by bending the stick and these horns are substantially arcs of a circle in plan. The upper and lower faces 4 and 5 of the central portion 1 and the horns 2 and 3 are straight, flat, parallel and hori- Zontal. The forward and rear faces 6 and 7 of the central portion 1 are vertical, flat,

straight and parallel. The forward and rear faces 8 and 9 of the horn 2 and the forward and rear faces 10 and 11 of the horn 3 are continuations of the faces 6 and 7 and are curved and concentric. The end faces 12 and 13 of the horns 2 and 3 are straight vertically and semi-circular in plan or around vertical axes, the flat sides of the semi-circles being straight across the grain of the wood, andthe face 12 connects the outer ends of the faces 8 and 9 and the face 13 connects the outer ends ofthe faces 10 and 11 and the faces 12 and 13 connect the ends of the faces 4 and 5. It is important that the stick be uniform and-homogeneous from the face 12 to the face 13.

The attaching riggings 14 and 15 are secured to the bumper at the ends of the straight central portion 1.

When desired, a metal cap 16 may be applied to each end of the bumper to cover the faces 12 and 13, as shown in Fig. 4. The cap 16 comprises an open-ended rectangular socket portion 17 having flat sides to fit the faces 4, 5, 8 and 9 or'4, 5, 10 and 11, and a semi-circular bottom 18 to fit the faces 12 or 13, said cap being cast .or built up to the desired form and'then driven tightly into place.

Especial attention is called to the semicircular faces 12 and 13, either bare or capped. The bare faces 12 and 13 are to be filled and polished to make them as smooth Patented June 29,1920.

as possible, the object of the shape and finish being to avoid the liability of the end faces of the horns catching an obstruction in going backward and thereby splitting the ends of the horns. Horns have been made with beveled faces and square faces and every time the automobile backs up to jam a horn against an obstruction the end of the horn splits but when the faces are made semi-circular in. plan and straight vertically the liability of catching an obstruction and splitting the end of the horn is reduced to a minimum and this trouble is entirely eliminated by placing caps upon the ends of the horns. V

I claim: 1. A bumper formed of a stick of wood and having a straight central portion and horns curved outwardly and backwardly from the ends of the straight central portion; the outer ends of the horns having faces semi-circular in plan and straight vertically; and-metal caps fitting the end faces.

2. A bumper formed of a stick of wood and having a straight central portion and horns curved outwardly and backwardly from the ends of the straight central portion; the outer ends of the horns being provided with metal caps.

In testimony whereof I have signed my name to this specification.
